Description

Technical Field

[0001] The utility model relates to the technical field of candle filters, and in particular to a candle filter which is convenient for maintaining and cleaning a filter screen. Background Art

[0002] Candle filtration is a relatively advanced, safe, efficient and pollution-free new filtering method. Candle filters have the characteristics of high efficiency and energy saving, airtight and high precision, easy maintenance, safety and reliability, and high degree of automation. They can be widely used in solid-liquid separation filtration in industries such as petroleum, plastics, electroplating, chemicals, ceramics, pharmaceuticals, and sugar making. Candle filtration has gradually replaced filter press and bag filtration to become the mainstream filtration method. The repeated use of the filter medium saves a lot of filter consumables; the sealed and firm cylinder ensures that there is no leakage in the production process; microcomputer automation control throughout the process not only maintains the continuity of enterprise production, but also greatly reduces the risk of production accidents while improving production efficiency and saving labor.

[0003] After searching, the announcement number CN211752913U discloses a candle filter. The candle filter includes a housing and an integral filter element. The integral filter element includes an upper fixing plate, multiple upper filter element sleeves, multiple candle filter elements, multiple clamping assemblies and a lower clamping plate. The upper fixing plate is detachably connected to the inner side wall of the housing. The upper ends of the upper filter element sleeves are respectively connected to the upper fixing plate. Each candle filter element is respectively sleeved on each upper filter element sleeve. The upper ends of the clamping assemblies are respectively connected to the lower ends of the candle filter elements. The lower ends of the clamping assemblies are respectively connected to the lower clamping plate. The candle filter provided by the utility model, when it is necessary to clean and replace the candle filter element, the integral filter element to be cleaned is taken out from the housing, and then the spare integral filter element is installed into the housing, so that the loading and unloading operations of multiple candle filter elements can be realized at the same time, and the disassembly and assembly are more convenient, thereby effectively improving the work efficiency.

[0004] However, after the candle filter is used for a period of time, a certain amount of dirt will adhere to the outer surface of the candle filter element inside the candle filter, causing its filtering effect to decrease. The design requires the filter element to be removed from the filter to complete the cleaning work. Frequent loading and unloading of the filter element not only increases the time-consuming overall cleaning work, but also during the cleaning process, the filter cannot continue to filter and can only wait until the installation is completed to perform filtering work, thereby greatly reducing the overall work efficiency.

[0024] See also Figure 1 and Figure 2 The utility model provides a technical solution: a candle filter that is easy to maintain and clean the filter screen, comprising a housing 1, a candle filter element 14 arranged in an annular shape in the housing 1 cavity for filtering, a confluence chamber 12 arranged at the bottom of the housing 1 and connected to the candle filter element 14, a discharge port 13 arranged at the bottom of the confluence chamber 12 for purifying the discharge, and a feed port 11 arranged at the side of the housing 1 for feeding the material, a driving assembly 2 is arranged at the bottom of the housing 1, the driving assembly 2 includes a synchronous rod 22 that can control forward / reverse rotation, a first conical tooth 221 and a second conical tooth 222 arranged on the outer side of the synchronous rod 22 for meshing rotation, a driven assembly 3 is arranged in the housing 1 cavity, and the driven assembly 3 includes a first conical tooth 221 and a second conical tooth 222 that rotate with the first conical tooth 22 1 and the second conical teeth 222 rotate synchronously with the driven threaded rod 31, and a lifting slide 33 is arranged on the outside of the driven threaded rod 31 to rotate with the driven threaded rod 31 and then move up and down. A cleaning component 4 is arranged in the cavity of the shell 1, and the cleaning component 4 includes a cleaning brush 42 for lifting and reciprocating cleaning of the candle filter element 14. A 44 for disassembly and installation is arranged at the connection between the cleaning component 4 and the lifting slide 33. This design solves the problem that the prior art requires frequent disassembly and installation of the cleaning filter element, which leads to an increase in the overall cleaning work time. At the same time, during the cleaning process, the filter cannot continue to filter and can only wait for the installation to be completed before filtering, thereby greatly reducing the overall work efficiency.

[0025] See also Figure 2 and Figure 3The driving assembly 2 includes a forward and reverse motor 21, which is fixedly mounted on the outer bottom of the shell 1. The output end of the forward and reverse motor 21 is fixedly connected to the synchronization rod 22. The middle of the outer surface of the synchronization rod 22 is fixedly connected to the first conical tooth 221. The end of the outer surface of the synchronization rod 22 is fixedly connected to the second conical tooth 222. The inner wall of the shell 1 cavity is symmetrically provided with track grooves 15.

The bottom of the driven threaded rod 31 is fixedly connected with the driven conical teeth 32, and the driven conical teeth 32 are independently meshed with the first conical teeth 221 and the second conical teeth 222.

[0026] See also Figure 2 and Figure 3 A first thread groove 331 is provided on one side of the middle of the lifting slide 33, and the first thread groove 331 matches the driven threaded rod 31. The lifting slide 33 is threadedly connected to the outside of the driven threaded rod 31 through the first thread groove 331, and the limiting blocks 332 are symmetrically fixedly connected on both sides of the lifting slide 33. The lifting slide 33 and the limiting blocks 332 are integrated and match the shape of the groove 15 of the rail groove 15. The lifting slide 33 is provided with a second thread groove 333 on the side away from the first thread groove 331. The two groups of driven threaded rods 31 rotate synchronously in the same direction to drive the lifting slide 33 threadedly connected to the outside thereof to move up and down. This design can prevent the cleaning disc 41 from tilting during the lifting and moving process. At the same time, the lifting slide 33 and the limiting blocks 332 form a whole that matches the shape of the groove 15 of the rail groove 15 to prevent it from positionally shifting during the lifting process.

[0028] The working principle and use process of the utility model are as follows:

[0029] When the external raw material enters the cavity of the housing 1 through the feed port 11, it will be filtered by the candle filter element 14 and then enter the candle filter element 14 until the filtered raw material flows into the confluence chamber 12, and the discharge of the filtered raw material is controlled by controlling the valve outside the exhaust port 13. In particular, when filtering the raw material through the candle filter element 14, the forward and reverse motor 21 can be started so that the output end of the forward and reverse motor 21 drives the synchronous rod 22 to rotate forward and reverse, thereby causing the first conical tooth 221 and the second conical tooth 222 located on the outer side of the synchronous rod 22 to synchronously mesh with the driven conical tooth 32 to rotate, thereby driving the driven The threaded rod 31 rotates back and forth, and the lifting slide 33 threadedly connected to the outside of the driven threaded rod 31 will synchronously drive the cleaning disc 41 installed in the cavity of the shell 1 to move up and down and reciprocate. At this time, the cleaning brush 42 located in the middle of the cleaning disc 41 will move up and down synchronously and scrape the dirt on the outer surface of the candle filter element 14. This design does not require frequent disassembly and assembly of the candle filter element 14 for cleaning, and can ensure that the candle filter element 14 can be cleaned in real time during the filtering process, which not only reduces the time-consuming cleaning process, but also reduces the problem of the shell 1 not being able to work due to the disassembly and assembly of the candle filter element 14.
